At least 30, if the betta is the only other thing you are planning on having in there. However, this does depend on the tetra - I'm working on tetras the size of neons or cardinals here.

-Imagines betta commanding army of tetra-
Type is important, neons stay small, some like penguins get pretty big. Also certain kinds (serpae, maybe others) should never be kept with a betta I believe.

+1. Serpaes are vicious little monsters.

Neon tetras. If you have neons then you could easily have 45 neon tetras in there with a male betta

I'd usually leave at least a gallon per fish.. Your betta may feel uncomfortable having that many fish around him, make sure there's a lot of plant for him to hide in.
